What’s New in CSF v3.2
Real-Time Exfiltration Defense and Recovery Enhancements for IBM z/OS
Modern mainframe environments face a paradox: they’re among the most critical systems in enterprise infrastructure, yet they often lack the modern cybersecurity features found in cloud and open systems.
MainTegrity CSF v3.2 addresses that head-on with a powerful update built for real-world security teams. If you’re managing IBM z/OS and need to detect data exfiltration, respond to privilege abuse in seconds, and recover without guesswork, this release delivers.
Designed for Security and Recovery Teams Who Need More Than Alerts
Security tools that only alert after damage has occurred aren’t good enough — especially on the mainframe. CSF v3.2 continues our mission to bring real-time prevention, automated recovery, and staff-guided investigation into one integrated system.
This version introduces advanced controls that help your team:
- Stop data exfiltration in progress based on transfer patterns, destinations, and thresholds
- Lock out compromised user IDs instantly, without waiting for human response
- Detect tampering attempts using tools like AMASPZAP or VTOC modification
- Block unauthorized z/OS operator commands before escalation occurs
These capabilities make it easier to trust what your system is doing in real time, instead of relying on logs and forensics after the fact.
Built for Visibility and Speed, Even for Lean Teams
Many mainframe shops today are lean or hybrid — with fewer RACF specialists and more DevSecOps oversight from cross-functional teams. CSF v3.2 helps those teams move faster and with more precision by providing:
- A browser-based interface with alert drill-downs and visual summaries
- Recovery assistant guidance that points to the best immutable backup based on attack timing
- Network behavior monitoring to detect anomalies without overwhelming with false positives
- Playbook-driven response actions embedded directly into the UI
Whether your team has 20 years of mainframe experience or is cross-training from other environments, CSF gives you the context to act decisively.
A Smart Upgrade for Organizations Facing Compliance Pressure
If you’re preparing for DORA, PCI DSS 4.0, or internal security assessments, CSF v3.2 can help close security gaps around privileged activity, change tracking, and recovery preparedness.
This release makes it easier to demonstrate:
- What happened during an incident
- When it was stopped
- How recovery steps were taken — and verified
With embedded reporting, audit trails, and alert history, CSF takes the burden off of manual documentation and supports your compliance story.
